Best Hiking Boots for Kids with Narrow Feet: Stop Heel Slippage and Blisters

Do your child’s hiking boots slip at the heel, or come back from the trail with blisters? Kids with narrow feet slide around in most hiking boots, because almost all kids’ boots are made medium or wide. As a certified children’s shoe fitter with over 10 years of experience, I’ll show you which hiking boots fit narrow feet, and two simple tricks to make almost any boot fit snugger.

Why Hiking Boots Are Hard for Narrow Feet

Kids’ hiking boots aren’t sold in narrow widths, and they aren’t labeled as narrow either. The only way to know which ones run slim is to fit a lot of them.

When a boot is too wide, a narrow foot slides forward going downhill and lifts out at the heel going uphill. That rubbing causes blisters, and the extra movement makes kids less steady on rocky or uneven ground.

What to Look for in Hiking Boots for Narrow Feet

A Narrow Platform

The platform is the base of the boot. A narrower base keeps the foot centered and stops it from sliding side to side.

A Snug Heel Counter

The heel counter is the firm cup at the back of the boot. A snug one holds a narrow heel in place, so it doesn’t lift out with each step.

Laces, Not Velcro

Velcro is convenient, but laces let you tighten the boot all the way up the foot and pull the heel into the back of the boot. For narrow feet, laces almost always fit better.

Waterproof, Lightweight, and Grippy

Like any hiking boot, look for a waterproof upper, a lightweight design so kids don’t tire out, and a lugged outsole for traction on dirt and rocks.

How to Get the Right Size

  • Don’t size up too much. For narrow feet, a boot that’s too long also feels too wide and slips at the heel. I usually recommend half a size larger than your child’s current foot size for hiking boots, rather than a whole size.
  • Check the toes. With the boot laced, your child’s toes shouldn’t touch the front. Feet swell on long hikes, especially in summer, and toes that hit the front going downhill can lead to blisters or bruised toenails.
  • Check the heel. Have your child walk up a step or a slope. Their heel shouldn’t lift out of the boot.
  • Try them on with hiking socks. Thicker socks take up room, which actually helps narrow feet.

Not sure of your child’s size or width? Here’s how to measure your child’s feet, or find a store near you in my list of children’s shoe stores by state.

Still Too Wide? Two Ways to Make Hiking Boots Fit

If a hiking boot still feels loose, these tricks work for most kids with narrow feet. I use them all the time in fittings.

1. Lace Them with a Heel Lock

This lacing method pulls the heel snugly into the back of the boot.

First Step: Lace the boot as usual, but stop before the last eyelet.
Second Step: Thread each lace into the top eyelet on the same side, making a small loop.
Third Step: Cross each lace through the loop on the opposite side, pull down to tighten, and tie as usual.

For more detail, see my guide to how to lace shoes to prevent heel slippage.

2. Add a Tongue Pad

An adhesive tongue pad sticks to the underside of the boot’s tongue. It fills extra space over the top of the foot and pushes the heel back into place. In my experience, it’s the most effective fix for narrow feet.

Stick the tongue pad on the underside of the boot’s tongue.

Another option: a full-length insole. An extra insole fills space from below. It helps a little, but I’ve found tongue pads work better. These insoles fit toddler size 4 to big kid size 7, and you trim them to size.

Frequently Asked Questions

Do kids’ hiking boots come in narrow widths?

Almost never. Instead, look for styles that run slim, like the Merrell Chameleon 7, and use laces and tongue pads to fine-tune the fit.

Why does my child’s heel slip in their hiking boots?

The boot is usually too wide or too long. Try a heel-lock lacing, a tongue pad, or a slimmer boot.

How do I make my child’s hiking boots fit narrower?

Lace them with a heel lock, add a tongue pad under the tongue, and wear thicker hiking socks.
